PROCESS OF TREATING GARBAGE.

SPECIFICATION forming part of Letters Patent No. 548,342, dated October 22, 1825.

Application iiled August 20,1894. Serial No. 520,757. (No model.)

To aZZ whom it may concern:

Be it known that I, J ULIUs 'WoDIsKA, a resident of New York, in the county and State of New York, have invented an Improved Process of Treating Garbage, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings.

The object of this invention is to utilize the material collected from kitchens, and known as garbage, which accumulates in large quantity in every town and city, andis with difficulty disposed of. To accomplish this I propose to take from the garbage, after it has been collected, the ashes and cinders which it may contain, and subject the residue to pressure for discharging the largest proportion of water, the remainder of the water being evaporated in a special drying apparatus. The dry garbage thus prod uced is now charged into retorts of gas apparatus, for manufacturing illuminating or heating gas therefrom, or it may be used for many other purposes. In this specification, however, I will confine myself to a description of the mode of making gas from garbage.

I am also aware that in order to render garbage iit for use in the retort, it should be so handled as not to emit disagreeable odors during the process of pressing. I have therefore provided a press of peculiar construction, which, while squeezing the material, collects the liquids that are extracted and conveys them through sealed passages to distant tanks, rivers, or other safe places of deposit. The next step in the treatment of the garbage is the drying process, which is carried on in a kiln, where it is heated, principally, through the waste heat from the gas-works, and which raises the temperature of the garbage to about the boiling-point of water, the vapors escaping through a chimney into the atmosphere.

In the accompanying drawings, Figure 1 represents a side elevation, partly in section, of my improved apparatus, showing the press, the drier or kiln, and the furnace containing the retorts. Fig. 2 is a sectional elevation of thegas apparatus, by itself, showing the carburetor, the gasholder, the purifier, the scrubber, the condenser, and the retorts all united. Fig. 3 is a horizontal section on the plane of the line c c, Fig. l. `Fig. 4 is an enlarged horizontal section of part of the press.

A represents a platform, upon which the garbage, after the ashes and cinders have been removed therefrom, is deposited. From this platform the garbage isput into the presscylinder B. This press-cylinder is composed, as appears from Figs. 3 and 4., of a series-of upright bars or ribs a a, which are at their 6o upper ends suspended from the platform A or other rigid support, and which are ranged in a circle and held in place by outer hoops b. The lower end ofthe ribs @have inwardly-` projecting hooks d. This press-cylinder B is contained within a housing C, which has an outlet D, leading tothe bottom of a river, to the ocean, to a suitable tank, or other proper place of deposit for the liquid which is expressed from the garbage.

The press-cylinder B contains two plungers E and F.v The lower plunger is rigidly attached to` the'plunger-'rod G, which passes loosely through the upper plunger F, and carries above the upper plunger a piston H within a hydraulic cylinder I, which cylinder is carried by and rigidly attached to the upper press-plunger F. The cylinder I may, if desired, be suspended by a rope or chain e from the derrick J, as shown in Fig. 1. From the 8o press the garbage passes through a suitable spout or conduit L into the kiln M, which by a suitable Hue f is connected with the fireplace of the gas apparatus N, so as to get the surplus heat therefrom, and which contains a chimney g for the discharge of products of combustion and another chimney h for the discharge 'of vapors that arise from the gar; bage. v

From the kiln M the garbage, properly dried, 9o is, or may be, fed into the retorts O O of the gas apparatus.

I will, Vbefore going further with the description of my invention, firstv describe the manner of using the press.

, In order to get the garbage into the press* cylinder B, the plunger F must be lifted out of said cylinder. To effect this water is forced under pressure through a suitable pipe c'into the cylinder I above the piston H. The press- I oo ure thus created within the cylinder I serves first to force the lower plunger E down uponand Water led, under pressure, through the,

pipe j into the lower part of the cylinder I that is to say, underneath the piston H. This will cause the upper plunger F to be forced downward and the piston H to be lifted, thereby causing the lower plunger to be also lifted, and, as a result, the contents of thev cylinder B will be squeezed togetherbetween the two plungers, the water which they contained escaping between the ribs a. a of the shell B into the housing C, and thence through the pipe D. Vhen the pressure has been sufficient on the garbage, the cylinder I, with the top plunger F, can be lifted out of the press `by means ot' the derrick, and by the same means when the top plunger F reaches the piston H the lower plunger E can be also lifted, so as to raise the compressed cake of garbage up to the level of the platform A, to enable the attendants to conveniently push it through the chuteL into the kiln M. Within this kiln, when the supply-door K and the discharge-door Zthereof are closed, the compressed garbage is exposed to sufficient heat to evaporate Whatever water may have `remained within it, at least to an extent sufficient to enable it to be used within thefretorts. The retorts O in the furnace N are arranged substantially as ordinary reto'rts are, and discharge the gas which is generated Within them, first, into the condenser P, then into the scrubber Q, then into the purifier R, and, finally, into the holder S, (see Fig. 2,) in manner substantially analogous to that pursued vin the ordinary manufacture of gas. From the holder S the gas to be utilized for heating purposes can be discharged ad Zibitum. A branch of the discharge-pipe T may lead back into the furnace N to heat the retorts, if desired. This branch is shown at T2 in Fig. 2. Any gas which is to be `used for illuminating purposes is conducted by the branch T3 of the discharge-pipe T into a carburetor. This carburetor may be of any suitable construction, but is shown in the present instance to consist of an outer vessel U, having a discharge-pipe min the upper portion and the supply-pipe T3 ,in the lower portion, and containing, also, the cap V.

l claim- The process herein described of treating garbage, which consists in pressing `the garbage and expelling the liquid therefrom by pressure, in then heating the garbage to further eXpel moisture therefrom, and in then subjecting the garbage to destructive distillation in a retort,substantially,as described.
